Not recomended
The keel should hold most of the weight on the trailer. Raising in off can deform the hull and during the rigors of trailering can cause all sorts of hurt, including separating bulkheads, supports and what not where they are glassed to the hull, no to mention just makes recovery more difficult and the road ride less stable. The glass is very thin in the bunk areas, but it most assuredly is not where the keel bolts through, and it was designed to take the weight. On the trailer your keel should be firmly on the board and the bunks pushed up to where they meet the hull to give it support and check any side to side rocking motion. You can call Hunter to be sure, but I'm certain this is a big no-no.
